Abstract

PROBLEM TO BE SOLVED: To easily detect motor lock by installing a judging part to judge whether a motor is locked or not based on the data of temperature detected by a temperature detecting means at the time when a prescribed time passes since power application to the motor to rotate a stirring means carried out after electricity application to a heater of a water content sensor. SOLUTION: A water content sensor 18 comprises a heater and a temperature detecting means of a thermistor to detect the temperature before power application to the heater and in the state that current is being passed to the heater. Operation control of a fan 34, a penal heater 51, and a stirring means 16 is carried out by a control part by computing the water content of an object garbage to be treated by the water content sensor 18. Whether the stirring means 16 is rotated due to power application to the motor 17 or whether the stirring means 16 is in motor lock state that the stirring means 16 is not rotated in spite of power application to the motor 17 is judged by a judgment part of the control part based on the data of the temperature detection. When it is judged that the motor is in moor lock state, energization to the motor 17 is stopped based on that.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for decomposing garbage using the power of microorganisms.

[0002]

2. Description of the Related Art Conventionally, sludge containing organic matter and water has been decomposed (fermented) using microorganisms so as not to affect the environment. Are known. In this garbage processing apparatus, a wood trash called a biochip is filled in a garbage processing tank as a garbage processing material. The garbage is introduced into the garbage processing tank from an input port provided in the garbage processing tank, and the garbage is fermented by the action of microorganisms living in the garbage processing material to be decomposed.

[0003] The conventional garbage processing apparatus is provided with a stirring means for stirring the garbage processing material in a garbage processing tank, and the stirring means is rotated by a motor. Then, by supplying electricity to the motor and rotating the stirring means, the garbage is stirred and mixed together with the garbage processing material, and the garbage is uniformly dispersed in the garbage processing material filled in the garbage processing tank. The garbage disposal material in each part in the garbage disposal tank is moved so that the garbage disposal is performed as uniformly and effectively as possible in the garbage disposal material.

[0004]

In the conventional example having the above configuration, the garbage is solidified as a lump in the garbage disposal tank, hindering the rotation of the stirring means, and energizing the motor. However, there is a problem that a so-called motor lock state occurs in which the stirring means does not actually rotate. When the motor is locked as described above, not only is there a problem that proper stirring cannot be performed, so that garbage disposal cannot be performed effectively, but also there is a problem that the motor is damaged.

Therefore, conventionally, it is conceivable to use a motor equipped with a motor lock detecting device for detecting a motor lock as a motor for rotating the stirring means, but in this case, an expensive motor is used. This causes the cost of the garbage processing apparatus to increase, and the use of a motor equipped with a motor lock detection apparatus causes a problem that the apparatus becomes large.

The present invention has been made in view of the above-mentioned problems of the conventional example, and provides a garbage processing apparatus capable of reliably detecting a motor lock of a motor rotating a stirring means with a simple configuration. The task is to do so.

[0007]

In order to solve the above-mentioned problems, a garbage disposal apparatus according to the present invention rotates a stirring means 16 provided in the garbage disposal tank 1 by a motor 17 so that the garbage disposal tank 1 can be rotated. In the garbage processing apparatus 13 configured to decompose garbage thrown into the garbage processing material 10 by stirring the filled garbage processing material 10, the garbage processing material 1
A water content sensor 18 for detecting a water content of 0 is provided in the garbage processing tank 1, and the water content sensor 18 detects a temperature before and after the heater 19 and the heater 9 are energized. And means 20 for detecting temperature.
A controller for controlling a fan for exhausting at least the exhaust gas in the garbage disposal tank to the outside by obtaining the moisture content of the garbage disposal material based on the temperature data from A determination is made as to whether or not the motor is locked based on temperature data detected by the temperature detecting means 20 after energizing the motor 17 in order to rotate the agitating means 16 after a predetermined time after energizing the heater 19 of FIG. It is characterized by comprising a portion 21a. With such a configuration, at least the water content sensor 18 provided in the garbage processing apparatus 13 is used to control the fan 34 for exhausting the exhaust in the garbage processing tank 1 to the outside. It is possible to detect whether the motor 17 that rotates the stirring means 16 is in the motor lock state.

[0008] The stirring by the stirring means 16 alternates between forward rotation of continuous rotation of at least two times and reverse rotation of continuous rotation of at least two times alternately. It is preferable to provide a control unit 21 for stopping the power supply to the motor 17 when it is determined that the motor is locked during the next reverse rotation or forward rotation. With such a configuration, even when the motor 17 attempts to rotate in one direction, even if the stirring unit 16 determines that the motor is locked without hitting the lump and rotating, the stirring unit 16 is moved in the other direction. When rotated, the lump may be moved by rotation in the other direction and may not be locked in the motor. In such a case, even if it is determined that the motor is locked, the energization of the motor 17 is not stopped. When the motor 17 attempts to rotate in one direction, the agitating means 16 hits the lump and does not rotate, but determines that the motor is locked. Next, when the motor 17 attempts to rotate in the opposite direction, the agitating means 16 does not rotate. When the agitating means 16 does not rotate due to the mass, the stirring means 16 rotates forward,
Regardless of the direction of reverse rotation, the stirring means 16
In this case, the power supply to the motor 17 is stopped.

The forward rotation rotates the stirring means 16 forward, and the reverse rotation of the motor 17 reverses the stirring means 17. The rotation of the stirring means 16 causes the garbage processing material 10 in the garbage processing tank 1 to rotate. Stir and supply air evenly to each part in the garbage processing tank 1 and evenly disperse and mix the garbage thrown into the garbage processing material 10 filled with the garbage in the garbage processing tank 1. Has become. The control of the rotation of the stirring means 16 is controlled by the control unit 21.

A surface heater 51 is attached to an outer surface of a lower portion of the garbage disposal tank 1. The surface heater 51 is for heating the garbage processing material filled in the garbage processing tank 1, and is heated by the surface heater 51 when the temperature of the garbage processing material is low. The surface heater 51 is controlled by a signal from the control unit 21. In the garbage processing tank 1, a garbage processing material made of a carrier such as sawdust-like woody chips called a biochip in which microorganisms have inhabited is placed. As the garbage disposal material, conventionally known woody flakes (for example, Japanese Patent Publication No. 2-30760) can be used.

A water content sensor 1 is provided inside the garbage processing tank 1.

Is input to the control unit 21. The temperature before turning on the heater 18a of the moisture content detection sensor 18 and the temperature of the heater 1
The temperature in a state in which 8b is turned on is detected by the temperature detecting means, and the moisture content of the garbage disposal material is obtained from the temperature change data by the temperature detecting means. The moisture content of the garbage disposal material 10 in the garbage disposal tank 1 is determined by the moisture content detection sensor 18, and the control unit 21 controls the fan 3 to be described later.
The operation control of the surface heater 4, the surface heater 51 and the stirring means 16 is performed.

Further, an auxiliary heater 30 for heating the air in the garbage processing tank 1 is provided above the garbage processing tank 1, and the auxiliary heater 30 provides a space above the garbage processing tank 1. The inside air is heated.
The opening of the upper cover 22b which forms the upper part of the case 22 is an input port 14, into which the garbage can be freely opened and closed by turning around a shaft attachment portion at the rear end. Cover 27 is provided.

At the upper end of the side wall 5 of the garbage disposal tank 1, an intake port 6 for supplying outside air into the garbage disposal tank 1 and an exhaust port for exhausting moisture and odor in the garbage disposal tank 1. 7 is provided. As shown in FIG. 1 and FIG. 2, the hanging piece 3 is provided inside the upper end of the side wall 5 of the garbage processing tank 1 through a small gap 4.
The intake piece 6 and the exhaust port 7 provided at the upper end of the side wall 5 of the garbage disposal tank 1 are hidden by the hanging pieces 3. A small gap 4 formed between the side wall 5 and the hanging piece 3 of the garbage processing tank 1 is open downward and communicates with the garbage processing tank 1.

An exhaust port 7 has a filter 11
Is installed. An exhaust passage 40 connected to the exhaust port 7
Is provided with a fan 34, and further provided with a deodorizing device 2 using a platinum catalyst. The deodorizing device 2 using a platinum catalyst heats the exhaust gas to deodorize, and is provided with a heater for this purpose. The deodorizing device 2 includes a dilution chamber 36,
The high-temperature exhaust gas heated by the deodorizing device 2 and deodorized by the platinum catalyst is diluted by stirring with the outside air introduced into the dilution chamber 36 and the dilution fan 35 in the dilution chamber 36, thereby reducing the temperature to a low temperature from the outlet 42. Exhaust to the outside.

In the garbage processing apparatus 13 configured as described above, when the garbage is put into the garbage processing tank 1, the stirring means 16 rotates to mix the garbage with the garbage processing material. Then, the garbage is decomposed by the action of microorganisms living in the garbage disposal material. By operating the fan 34, exhaust such as moisture and gas generated by the garbage processing in the garbage processing tank 1 is exhausted to the outside through the exhaust passage 40, and at the same time, the fan 34 is operated and exhausted. At the same time, the outside air passes through the intake path 28 and
Is supplied into the garbage processing tank 1, whereby fresh oxygen is supplied to the garbage processing material, thereby activating the action of microorganisms. At this time, the moisture content sensor 1
The operation of the fan 34, the surface heater 51, and the stirring means 16 is controlled by the control unit 21 by obtaining the water content of the garbage processing material 10 in the garbage processing tank 1 by 8.

The detection of the water content by the water content sensor 18 is performed each time the motor 17 for rotating the stirring means 16 is driven. (A) and (b) in the operation explanatory diagram of FIG.
FIG. 4C shows the timing of the mutual operation of the water content sensor 18 and the turning on and off of the motor 17, and FIG.
FIG. 4 shows a time chart of the sensing period of the temperature detecting means 18b composed of the thermistor of the moisture content sensor 18, and FIG. 4B shows a time chart of turning on and off the heater 18a of the moisture content sensor 18, and FIG. 4A and 4B show time charts for turning on and off the motor 17, and FIGS.
As shown in (c), the motor 17 is turned on, the stirring means 16 is rotated, and the garbage processing material in the garbage processing tank 1 is stirred a predetermined time before the first time by the temperature detecting means 18b of the water content sensor 18. And the heater 18a of the moisture content sensor 18 is turned on at the same time as the end of the first temperature detection,
A certain time before turning off the heater 18a, the water content sensor 1
8, the second temperature detection is performed by the temperature detection means 18b.
Is turned on, and then the heater 18a is turned off and the motor 17 is turned off.
Off at the same time. Here, determined between the detected temperature T ₂ of the second time by the temperature detecting means 18b, the difference between the detected temperature T ₁ of the first, that is, the water content of the food waste material 10 from the T ₂ -T _1, the control unit 21 This controls the operation of the fan 34, the surface heater 51, and the stirring means 16. That is, a plurality of operation modes such as a weak operation, a normal operation, and a strong operation are provided, and the operation mode is automatically switched based on the moisture content data obtained as described above.

In the present invention, as shown in FIG. 4A, after the motor 17 is turned on by the temperature detecting means 18b of the water content sensor 18, a third temperature detection is performed immediately before the motor 17 is turned off. It has become. Therefore, before turning on the heater 18a of the moisture content sensor 18, the temperature detecting means 1
When the heater 18a is turned on after the first temperature detection by 8b, the temperature rises until the second temperature detection by the temperature detecting means 18b as shown by the solid line in FIG. 4D. However, when the motor 17 is turned on and the agitating means 16 is rotated immediately after the second temperature detection, the garbage processing material in the garbage processing tank 1 is agitated, whereby the garbage processing material in the water content sensor 18 is also agitated. As a result, as shown by the solid line in FIG. 4D, the temperature decreases while the motor 17 is turned on. Therefore, immediately before the motor 17 is turned off, the temperature is detected by the temperature detecting means 18b of the water content sensor 18 for the third time. Temperature T for temperature detection
₃ becomes lower than the _second detection temperature T2. However, now, when the stirring means 16 is not rotated due to the lump of garbage in the garbage processing tank 1 and is in a motor locked state, even if the motor 17 is turned on, the agitation means 16 is not rotated. As a result, the rotation is hindered and the motor does not rotate (i.e., the motor is locked). Therefore, as shown by the broken line in FIG. The data does not show a value as shown by the solid line above, but shows a higher temperature. Therefore, based on the data of the third temperature detection, the determination section 21a of the control section 21 turns on the power supply to the motor 17 to rotate the stirring means 16 or turns on the power supply to the motor 17. Nevertheless, it is determined whether or not the motor is in a locked state in which the stirring means 16 does not rotate.

Here, as described above, the determination unit 21a of the control unit 21 determines that the motor is locked, and based on the determination, stops the power supply to the motor 17 and informs that the motor is locked. The notification means notifies the motor lock state. In stopping the energization of the motor 17 and notifying the motor lock by the notifying unit, the stop of the energization to the motor 17 and notification of the motor lock by the notifying unit may be performed by one determination of the motor lock state. Alternatively, it is also possible to stop the energization of the motor 17 or to notify the motor lock by the notification means 70 by determining the motor lock state two or more times.

In the embodiment shown in FIGS. 5 and 6, there is shown an example in which when the determination of the motor lock state is continued twice, the power supply to the motor 17 is stopped and the notification of the motor lock by the notification means 90 is performed. . In this embodiment, FIG. 5A corresponds to FIG. 6A, and FIG.
5 (b), FIG. 5 (c) and FIG. 6 (c), FIG. 5 (d) and FIG. 6 (d), FIG. 5 (f) and FIG. ) And correspond. FIG. 8 is a control block diagram of the present embodiment.

In this embodiment, the control unit 2 controls the rotation of the motor 17 so as to alternately rotate the motor 17 at regular intervals at least two times, ie, forward rotation and at least two times continuous rotation.
1 is controlled. Therefore, even if the motor lock state is determined by the determination unit 21a of the control unit 21 based on the data of only one rotation (forward rotation or reverse rotation) of the motor 17, the power supply to the motor 17 is immediately stopped. If such control is performed, the following problem occurs. In the present embodiment, the motor is determined to be locked when the motor rotates forward or reverse, and the motor is locked when the motor is determined to be locked during the next reverse rotation or normal rotation. 17
The power supply to is stopped.

That is, it is assumed that a litter B of garbage that impedes the rotation of the stirring means 16 is generated in the rotation range of the stirring means 16 between the first forward rotation and the second forward rotation. I do. In the state of FIG. 5A, a control signal is sent to perform the first forward rotation, and the motor 1 is rotated as shown in FIG. 6A.
When the power is supplied to the motor 7, there is nothing that hinders the forward rotation of the stirring means 16, so that the stirring means 16 rotates 360 ° (that is, the motor 17 rotates forward as shown in FIG.
The first determining unit 21a does not determine that the motor 17 is in the motor locked state.

Next, after a certain period of time from the state shown in FIG. 5A, a control signal is sent to perform the second forward rotation and the motor 17 is energized as shown in FIG. 6B. 5
As shown in (b), the stirring means 16 rotates in the direction of the arrow from the state of the broken line (that is, the motor 17 rotates forward as shown in FIG. 6 (b)), hits the litter B and stops at the state of the solid line. Further rotation is prevented. FIGS. 5B and 6
In the stage (b), the motor 17 performs the second forward rotation by a certain angle and the stirring means 16 rotates by a certain angle.
The determination unit 21a of the control unit 21 does not determine that the motor 17 is in the motor locked state.

Next, after a certain period of time from the state shown in FIG. 5B, a control signal is sent to perform the first reverse rotation, and the motor 17 is energized as shown in FIG. 6C. 5
The stirring means 16 rotates in the reverse direction from the state shown by the broken line in FIG. 6C to the state shown by the solid line (that is, the motor 17 rotates in the reverse direction as shown in FIG. 6C). Further rotation is prevented. FIGS. 5C and 6
In the stage (c), the motor 17 performs the first reverse rotation by a certain angle and the stirring means 16 rotates by a certain angle.
The determination unit 21a of the control unit 21 does not determine that the motor 17 is in the motor locked state.

Next, after a certain period of time from the state of FIG. 5C, a control signal is sent to perform the second reverse rotation and the motor 17 is energized as shown in FIG. 5
As shown in FIG. 6D, the agitating means 16 hits the garbage lump B and cannot reversely rotate in the direction of the arrow (the motor 17 does not rotate as shown in FIG. 6D).
Thus, it is determined that the motor 17 is in the motor locked state.

Next, after a certain period of time from the state of FIG. 5D, a control signal is sent to perform the first forward rotation and the motor 17 is energized as shown in FIG. 5
6E, the stirring means 16 rotates forward from the state shown by the broken line to the state shown by the solid line (that is, the motor 17 rotates forward as shown in FIG. 6E), and rotates to the state shown by the solid line to hit the lump B of garbage. Further rotation is prevented. 5 (e) and 6
In the stage (e), the motor 17 performs the first forward rotation by a certain angle, and the stirring means 16 rotates by a certain angle.
The determination unit 21a of the control unit 21 does not determine that the motor 17 is in the motor locked state.

Next, after a certain time from the state of FIG. 5 (e), a control signal is sent to perform the second forward rotation and the motor 17 is energized as shown in FIG. 6 (f). 5
As shown in (f), the stirring means 16 hits the litter B and cannot rotate in the forward direction in the direction of the arrow (the motor 17 does not rotate as shown in FIG. 6 (f)).
Thus, it is determined that the motor 17 is in the motor locked state.

As described above, the motor lock state can be determined only at the time of the second forward rotation of the two forward rotations and at the time of the second reverse rotation of the two reverse rotations. . By the way, if the agitating means 16 is a motor lock that cannot be rotated at the time of the second forward rotation or the second reverse rotation because the stirring means 16 is obstructed by a lump of garbage or the like.
Of the motor 17
When the motor 17 is turned on and the first reverse rotation control (or the first forward rotation control) is performed after a certain period of time following the second normal rotation control (or the second reverse rotation control), At the time of the first reverse rotation (or at the time of the first forward rotation), the stirring means 16 rotates in the reverse direction. At this time, the stirring means 16 rotates the garbage processing material by the reverse rotation (or the normal rotation), At the time of the second forward rotation (or the second reverse rotation), the litter or the like of the garbage that has hindered the rotation of the stirring means 16 moves or is loosened and scattered. When the second reverse rotation control (or second forward rotation control) of the motor 17 is performed, the agitating means 16 can perform reverse rotation (or forward rotation) without any trouble.
Is not determined to be the motor lock.

Therefore, as described above, the determination unit of the control unit 21 only performs the second forward rotation of the two forward rotations and the second reverse rotation of the two backward rotations. 2
1a, it is determined that the motor is in the locked state. As described above, after one determination of the motor locked state, the agitating means 16 is used in the first forward or reverse rotation of the next motor.
May rotate to move a lump of garbage or the like that is the cause of the motor lock, or may loosen and scatter the garbage to release the motor lock.
The control by the control unit 21 so that the power supply to the motor 17 is stopped every time the motor lock state is determined may not correspond to the actual state. In other words, the motor lock may be released by the rotation of the motor in the reverse direction after the motor lock is determined. Therefore, the power supply to the motor 17 is stopped every time the determination unit 21a determines the motor lock state. Is less preferred.

Therefore, in the present embodiment, the motor 17 is stopped when the motor lock is determined during the forward rotation or the reverse rotation, and when the motor lock is determined during the next reverse rotation or the forward rotation. It is controlled by the control unit 21. That is, at the time of the second forward rotation of the motor 17 (or at the time of the second reverse rotation), the determination unit 21a determines that the motor is locked, and passes through the next first reverse rotation (or the first forward rotation). When it is determined that the motor is locked at the second reverse rotation (or at the second forward rotation), the power supply to the motor 17 is stopped because the motor lock cannot be actually rotated forward or reverse. It is. In this case, an arbitrary notification means 70 may notify that the motor is locked.
